1. MOUNTING

When the retraction tank is made locally, finish it so
that the welding bead does not protrude on the inner
surface of the tank. The tank guide will hit the bead,
causing motor born-out. The gap between the tank
and tank guide is 1 mm. Also when installing the
tank, orient the welding bead so it faces the port or
starboard direction.
1.1.2 Installation of the retraction tank
The retraction tank is 1000 mm in length as supplied. Shorten the tank referring to the
table below so the transducer fully protrudes beyond the keel when it is lowered. Refer
to the installation procedure at the back of this manual for details.
